Visonic MCT-302 Wireless Door Window Contact Transmitter









PowerCode Wireless Magnetic Contact

MCT-302 is a fully supervised PowerCode magnetic contact transmitter, designed primarily for protecting doors and windows using a built-in magnetic contact that operates in conjunction with a magnet to detect the opening and closure of a door or window. This highly reliable top-performance wireless device is easy to install and operate in a wide range of residential and commercial environments.


An additional hard-wired, end-of-line (EOL) protected input can be used, with normally open (NO) and normally closed (NC) pushbuttons, sensors, contacts, switches and other detection devices, for a variety of security and control applications. 

When activated, the magnetic contact and the auxiliary input initiate an individual 24-bit PowerCode ID message, which identifies it to the target receiver as a separate transmitter. Each ID code is randomly selected from 16 million possible combinations, and is therefore unique and virtually impossible to accidentally reproduce.

A smart anti-collision algorithm prevents signal jamming by simultaneous transmission from multiple devices. Periodic transmission of supervision signals is used to confirm system connectivity at all times.

These unique top quality devices are available in several optional frequencies in compliance with European, U.S. and other international standards. Each transmitter is powered by a standard long-life lithium battery, which is constantly monitored, with automatic reporting to the receiver when the battery needs to be replaced.
